CodeCache for inline script: Run some benchmark.

Project Member Reported by arthurso...@chromium.org, Dec 18 
The browser process commit a navigation by sending the response's header and response'body to a renderer process. In the renderer process, it should start loading immediately. Currently, this is not the case. There is now Javascript Code caching for inline scripts. It blocks loading and waits for an IPC roundtrip with the browser process (and network process) for a potential cached code.

I would like to benchmark a few things:
1) Instead of blocking the loader, block only the parser. It would allow the navigation to commit quickly.
2) Instead of blocking the loader, block only the parser when it encounters a inline script.
3) Request code cache earlier, when the navigation is still in the browser process.
4) Stop using code caching for the main resource.

1) and 4) are easy to do, so I will try them first.
